[ d_cvId ]
) 
=> t_usageType / nil

Description

Returns the current hierarchical cache usage for a given design, if specified. If not specified, it returns the usage for the current session. The subset of operations included in both the design and session usages is enabled for the design.

Value Returned

t_usageType	The operations that the hierarchical cache may be used for. The loadOnly operation indicates that the hierarchical cache is used when loading the design hierarchy. The saveOnly operation indicates that the hierarchical cache is saved together with the cellview that contains it, which is typically the top design in the hierarchy. Valid returned values: none, saveOnly, loadOnly, saveAndLoad
nil	An error occurred.

Example

dbSetHierCacheUsage("saveOnly")

dbGetHierCacheUsage()

=> "saveOnly"
